 Data on sea lion dives was used to construct a model that represents the process of sea lion exit from nets via Sea Lion Exclusion Devices.  The model produces estimates of total sea lion deaths as a result of interactions with trawls, including any animals that run out of air after exiting the net.  Under a range of assumptions, the results suggest scalers of between 1.2 and 1.5 for estimating total deaths from observed deaths.
